I have had my 2015 Navara ( Silverline Edition) for 7 years, Its been a magnificent car, only done 97,000 Klms so far,
Reading through the service book as I'm nearing 100,000klms, I thought I may have to change the diff oils and auto trans oil, but only have to do timing belt?
When has/does anyone else change their diff oils.
It has the YD25DDTi
FYI never really does hard work, mostly towing tandem trailer with firewood,

Welcome to the forum.

My diff (and gearbox and transfer case) oils get changed every 40,000km. My timing chain hasn't been touched - it's been checked, along with the tensioners. Engine oil is changed every 10,000km. 380,000km on the engine so far.

The newer gearboxes aren't supposed to need oil changes but it doesn't hurt. It's certainly a pain in the butt to do, the filling point is underneath, you have to pump the oil upwards into the gearbox!
